Fail:
A red LED indicates the bump test or calibration failed.
If a bump test or calibration fails, check the calibration gas pressure and try again. If it fails again, it is
possible the sensor is depleted and must be replaced.

Whenever a bump test or calibration is performed, the buzzer and LEDs on the ToxiRAE 3 are tested.
If the instrument passes the tests for the buzzer and LEDs, then there is no special indication.
However, if either the buzzer or LEDs test fails, the Bump LED glows green and the Service LED
glows red.
